RED LIGHT ENFORCEMENT

Safe public transportation is a global concern, especially in responding quickly to traffic accidents. In a modern society with increased mobility, red light violations are a major factor in traffic tragedies. Every year, 21.5% of all traffic accidents are caused by running red lights. The Dahua Red Light Enforcement Solution reduces accidents to create safer and more secure roads for citizens.

? Solution Details

At the core of the Red Light Enforcement Solution is a system that synchronizes the status of red light signals with the triggering signal to cameras. When a violation occurs, the Dahua all-in-one capture camera takes three images of the violation to be used as evidence. These images include the vehicle license plate, status of traffic signal, and an overview of the scene. Afterwards, the platform and storage collects the data from each camera and distributes it to client operators for further processing. Edge storage devices ensure data from the cameras is saved, even in the event of transmission failure.

TRAFFIC SIGNAL CONTROL

The Dahua VACS Solution is a system that can extend traffic light intervals according to the detected vehicle queue length of road intersections. It adopts a traffic flow camera to detect information such as traffic flow, headway, average speed, occupancy, and queue length. It effectively improves traffic conditions through adjustments to make traffic flow faster. In addition, the system works independently and does not require a central software platform.

? Solution Details

>> Traffic Data Collection

The collection of traffic data helps manage traffic signals and provide for more efficient signal adjustments based on real traffic data. Traffic authorities can use real-time data to better understand current road conditions and enhance dynamic green light management, which can greatly reduce vehicle idle times. In the morning and evening rush hours, signal times can be adjusted according to actual conditions to provide more time for vehicles on busier roads.

>> Adaptive Signal Control

The traffic flow camera detects vehicles in pre-defined lanes and sends the length of vehicle queues to the controller through an Ethernet connection. The controller then triggers and automatically improves signal timings.

REAL TIME TRAFFIC STATUS DISPLAY

Millions of people deal with traffic congestion on a daily basis. The roadways leading into and out of most major cities can become gridlocked due to accidents, road construction, or simply a high number of cars on the road.

? Solution Details

>> Traffic Data Collection

Traffic data is collected by traffic flow cameras using non-intrusive virtual loops where detection is done through advanced computer algorithms and does not involve any road work as in the case of an inductive loop. It can cover 1-4 lanes at a time, and has a 99% detection accuracy at speed below 80km/h.

>> Information Dissemination

Another core system function is information dissemination, which can also help guide traffic with these additional information types:

Background

Many signal controllers are unable to automatically adjust signal timing based on real-time traffic flows, which could lead to long traffic queues during rush hour, requiring more police resources to direct traffic.

>> Traffic Data Processing

An advanced traffic flow information analysis algorithm gets and analyzes a city's traffic conditions in real time and displays results on special road signs in colors of red, yellow, and green to represent the speed of traffic flow. It serves as a guide to help drivers select the best travel route, easing overall traffic congestion.

PARKING VIOLATIONS

Illegal parking is the act of parking vehicles in restricted areas such as fire lanes, crosswalks, sidewalks, in front of fire hydrants, etc

System Overview

? Solution Details

The Dahua Parking Enforcement solution is a system for detecting parking violations. It is used for simple and effective monitoring of parked cars in selected and precisely defined zones. It can effectively monitor areas where stopping or parking is prohibited, or areas with a limited parking time. Dahua devotes itself to safeguarding pedestrians, easing the burden on public transportation, and helping the disabled community.

Features and Benefits

Background

Millions of commuters, students, parents, and the elderly rely on bus transportation every day to get to where they need to be. Buses help reduce traffic congestion and air pollution because they provide a more efficient way of moving people from one point to another. However, cars and trucks travelling and parking in bus lanes reduces the efficiency of buses and creates unneccessary congestion.

? Solution Details

This figure shows a camera with License Plate Recognition (LPR) enabled, capturing both the license plate number and a color snapshot of the vehicle crossing into the bus lane. The system then uploads the images to the CyberCity platform along with the vehicle plate number. The business platform then collects the vehicle list from the CyberCity and checks to see if they are on the list of permitted vehicles provided by the vehicle registration database. These records can then be verified and traffic tickets can be issued after verification and approval. The DSS can also sort vehicles by custom rules or plate color, if provided.

? Search and fuzzy search by plate/time/type of Vehicle.

? Show plate/record time/processing pictures/linkage video.

? Supports live monitoring.

? Features and Benefits

? Fully automated.

? Reduces traffic enforcement overhead costs.

? Speeds up bus transit times.

? Video-based vehicle classification to monitor different vehicles. No Additional sensor is needed.

? Improves carbon emissions.

SPEEDING DETECTION

Background

Most governments all over the world prioritise the improvement of road safety. One of the available tools for influencing the behaviour of road-users is traffic enforcement – and in particular speed measurement.

There are currently several ways to measure speed - section speed enforcement and point speed enforcement. Section speed enforcement, in contrast to point speed enforcement (for example, radar boxes) , has the advantage of measuring speed on a longer road stretch, preventing abrupt speed reduction at certain points. Point speed enforcement has the advantage of increased mobility so that traffic police can move to different points whenever necessary.

? Solution Details

The Dahua Point Speed Enforcement solution can effectively help transportation authorities detect vehicles which break the speed limit in all types of weather conditions. The system features an all-in-one design which makes it easy to use and install. It consists of an 8MP CCD camera and multi-target tracking radar which provide an accurate instant speed measurement of each passing vehicle with high definition images. What’s more, the IR flash lamp ensures excellent imaging capabilities even at night.

? Features and Benefits

>> Supports measurement of multiple vehicles in different lanes with high-precision 3D radar.

>> In addition to speed, cameras can also capture details such as plate number, vehicle type, and lane number.

>> High definition cameras can operate around-the-clock.

>> Long battery life, touch panel, and compact design provide better on-site enforcement.

>> Easy setup, instant deployment.

>> Uses wired / wireless(Wi-Fi, 4G) network to forward data back to control center.

? Solution Details

The Dahua ANPR camera captures the plate number and time at both the section start and end, and forwards this information to the platform. The platform then evaluates the average velocity of each passing vehicle. The margin of error of velocity detection diminishes as section length increases. The recommended distance of sections is 2-5km, of which accuracy reaches up to 99.8%. Multiple velocity limits can also be set for different types of vehicles.

? Traffic Management Server Support
